Automated design of minimum drag light aircraft fuselages and nacelles

The constrained minimization algorithm of Vanderplaats is applied to the problem of designing minimum drag faired bodies such as fuselages and nacelles. Body drag is computed by a variation of the Hess-Smith code. This variation includes a boundary layer computation. The encased payload provides arbitrary geometric constraints, specified a priori by the designer, below which the fairing cannot shrink. The optimization may include engine cooling air flows entering and exhausting through specific port locations on the body

Employment Retention Policy

This Report investigates the potential for a statutory model of employment retention leave. A Private Members Bill (HC Bill 2006-07) [79] currently in progress through Parliament would, if enacted, offer disabled employees the right to paid leave for employment assessment, rehabilitation or re-training

Reformulation in planning

Reformulation of a problem is intended to make the problem more amenable to efficient solution. This is equally true in the special case of reformulating a planning problem. This paper considers various ways in which reformulation can be exploited in planning

Mechanical behaviour of functionally graded carbon nanofibre/phenolic nanocomposites: numerical modelling and experimental validation

In this study, a finite element-based model was developed to investigate the mechanical behaviour of functionally graded carbon nanofibre (CNF)/phenolic nanocomposites. Four functionally graded nanocomposites (FGNs), a non-graded nanocomposite (NGN), and a pure phenolic with the same geometry and total carbon nanofibre content were designed and fabricated. Flexural tests were conducted to validate the proposed finite element model. Close agreement was obtained between experimental results and numerical predictions. The results showed that flexural modulus can be improved about 45% by controlling the CNF content across the thickness of the samples

Overcoming Distance and Time: Online Supervisor Training in Contextual Education Programs

Faced with the need to have well trained supervisors for students who were serving in ministry in locations varying distances from the seminaries, field education staff developed a way of training and communicating with supervisors serving some physical distances from the seminaries. The process has worked sufficiently well so that they are expanding the program to include all pastors who serve as intern supervisors
